sure the Particulate Filter with the NOx Reduction Catalytic Con‐

verter Is Installed without Tension:
1.

Position the lower bracket with the nuts on the cylinder block

and on the particulate filter. (Do not tighten the nuts.)

2.

Position the new clamp with a new gasket between the par‐

ticulate filter and turbocharger (do not tighten the clamp):

• Make sure the clamp is in the correct installation position. Re‐

fer to

⇒ “1.3 Clamps and Exhaust Gas Temperature Sensor Instal‐

led Position”, page 368

 .

3.

Install the EGR filter -item 9- 

⇒ Item 9 (page 399)

 .

4.

Position a new clamp between the particulate filter and EGR

filter (do not tighten the clamp):

• Make sure the clamp is in the correct installation position. Re‐

fer to

⇒ “1.3 Clamps and Exhaust Gas Temperature Sensor Instal‐

led Position”, page 368

 .

5.

Mount the particulate filter on the upper bracket but do not

tighten the bolt yet.

– Tighten the mounting elements in the following sequence:
6.

NOx reduction catalytic converter mounting on the sub‐

frame:

7.

Clamp between the particulate filter and turbocharger.

8.

Lower bracket to the cylinder block:

9.

Lower bracket to the particulate filter:

10. Upper bracket to the particulate filter:
11. Upper bracket to the cylinder head:
12. Clamp between the particulate filter and EGR filter:
• Tightening specification. Refer to

⇒ “1.2 Overview - Particulate Filter with NOx Reduction Cat‐

alytic Converter”, page 360

 .

If the particulate filter was replaced:
– Remove the transport and protective packaging on the de‐

coupling element between the particulate filter and NOx re‐

duction catalytic converter.

Further installation is the reverse order of removal. Note the fol‐

lowing:
• Make sure the line connections are secure.
• Tightening Specifications. Refer to

⇒ “1.2 Overview - Particulate Filter with NOx Reduction Cat‐

alytic Converter”, page 360

Refer to ⇒  Suspension, Wheels, Steering; Rep. Gr.  40 .

Vehicles with Manual Transmission:
• Tightening specification. Refer to ⇒  6-speed Manual Trans‐

mission 02Q; Rep. Gr.  34 .

Vehicles with DSG

®

 transmission:

• Tightening specification. Refer to ⇒  6-Speed Dual Clutch

Note

If the particulate filter was replaced, then the adaptation of the

soot load measurement must be set to “0”. Refer to Vehicle Di‐

agnostic Tester “Guided Functions”.

– Perform a road test. The vehicle must be aligned if the steering

wheel is »crooked«. Refer to ⇒  Suspension, Wheels, Steer‐

ing; Rep. Gr.  44 ; Wheel Alignment .

the NOx Reservoir or Slip Catalyst
– Insert the gasket -2- with the angled tab -B- in the notch -A-

on the NOx reservoir or slip catalyst -1-.

– Insert the Exhaust Door Control Unit - J883- -3- with the re‐

taining tab -C- in the notch -A-.

Installation Position of the Clamps Between Exhaust Door Control

Unit - J883- and NOx Reservoir or Slip Catalyst.
– Install the new clamp so the clamping bolt is opposite the Ex‐

haust Door Control Unit - J883- housing and the -45 ± 10°-

angle is maintained.

Clamping Sleeve Installation Position
– When installing clamping sleeve, ensure that the bolt end

-arrow- does not project beyond the lower edge of clamping

sleeve:

• Threaded connection points toward the right.
• Tighten the threaded connections equally to 23 Nm.
